ENGINE.

Application filed July 5,

To all whom it may concern:

Be it known that I, J osnrn H. Koran, a citizen of the United States, residing at Arcadia, in the county of Los Angeles and State of California, have invented new and useful Improvements in Engines, of which the following is a specification.

This invention relates to engines of the rotary type and has for an object the provision of an engine of this character which is constructed so as to impart a continuous impulse to the rotor and consequently to the drive shaft so as to increase the speed and power generated by a given amount of fuel in an engine of a given size, resulting in the production of an engine which will be economical of operation and which will 0ccupy a minimum amount of space.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a side elevation of an engine constructed in accordance with the invention.

Figure 2 is a sectional view of the same.

Figure 3 is a section on the line 33 of Figure 2.

Figure 4c is a similar view on the line H of Figure 2.

Figure 5 is a detail view of one of the pistons.

Referring specifically to the drawings, wherein like characters of reference denote corresponding parts, the reference character 10 indicates the casing of the engine which is preferably formed in separate sections which are bolted together as shown at 11. The casing 10 is provided upon opposite sides with a sleeve 12 which extends outwardly to provide a bearing 13 by means of which the said casing may be rotatably supported. The sleeve 12 also extends inwardlyas shown at 14:, for a purpose which will be hereinafter apparent. Operating within the casing 10 is a rotor 15, which is supported upon a shaft 16 which extends through the sleeves 12. This rotor'is provided with a plurality of pockets 17, formed with restricted openings 18. Operating within these pockets are abutments 19, one end of which engages the inner periphery of the casing 1921. Serial No. 482,466.

10, while their opposite ends extend within the pockets 17. The abutments 19 extend entlrely across the wldth of the casing and have secured adjacent each of then side ends,

segmental arms 20 which engage over and extend partly around the inwardly projecting portion 14: of the sleeve 12. This sleeve thus provides an eccentric mounting for the arm 20 and during the operation of the in vention, causes the abutments to engage the W5 inner periphery of the casing 10 during the entire revolution. of the rotor within the casing. Chambers 21 are thus formed within the casing which are adapted to receive the steam or other motive agent and force the l abutments around the bearing provided by the inwardly extending portion 14: of the sleeve 12 and impart movement to the rotor 15. As the shaft 16 is secured to the rotor,

the former will be caused to rotate and power may be taken from the shaft by any desired means.

One of the sleeves 12 is provided at its inner end with a head 22, having an intake port 23 and an exhaust port 24. During the to revolution of the inner end of the passages 25, so that one of these passages is always in communication with the intake and the steam or other motive agent is always being supplied to one of the chambers 21, so that a. constant impulse is imparted to the rotor 15. The exhaust port 2 1 is also of arcuate formation and extends for an appreciable distance in the path of travel of the passages 25, the said passages being alternately intake and exhaust ports, and due to the 1 length of the exhaust port 24:, the chambers 21 are thoroughly exhausted before the outer periphery of the rotor 15 contacts with the inner periphery of the casing 10 during the eccentric rotary motion of the former within me the latter.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly no In the drawing six 85 all Within the scope of the appended claims.

Having described the invention What is claimed i" 1. A rotary engine embodying a rotatably mounted casing, a rotor mounted to revolve eecent-rically Within the casing, a concentrically arranged sleeve extending Within each end of the easing, a plurality of radially arranged abntments contacting With the inner 10 periphery of the casing, segmental arms can ried by the ahutnients and bearing upon said sleeves and substantially lliptical pockets formed Within the rotor and receiving said abntments to permit of relative sliding and rocking movement, inlet anfly exhaust ports and passages extending through the rotor and communicating With the interior of the casing, said passages alternately registering with the inlet and exhaust ports.

2. A rotary engine embodying a rotatably mounted casing, a rotor mounted to revolve eccentric-ally Within the casing a plurality of abutments arranged concentrically Within the casing, pockets formed in the rotor and receiving said abutments to permit or relative sliding movement, whereby it plurality of fluid expansion chambers are provided Whose end Walls are defined by the abutments, hearing sleeves carried by the casing, a stationary head closing the inner end of one or the sleeves and having inlet and exhaust ports therein and passages extend through the rotor and communicating with the interior of the casing, said passages alternately registering with the inlet and exhaust ports. 7

In testimony whereof I affix my signature.
